;HISTORY:
|
|
;keep dates in european format (dd/mm/yyyy), please
|
|
; '!' means big changes
|
|
;
|
|
;to-do:
|
|
; more vendors
|
|
; vendor's website
|
|
; Subsystem id and Subsystem vendor id detection
|
|
|
|
; Full device detection (like "ATI Radeon 9200") will increase app
|
|
; size a lot and probably it is function of particular drivers

; * comments to various parts of the code
|
|
; optimized
